ITEM 2.        ACQUISITION OR DISPOSITION OF ASSETS

     On January 31, 1997, DI Industries, Inc., a Texas corporation (the
"Company"), completed the acquisition of the operating assets of Flournoy
Drilling Company ("Flournoy") and elected Mr. Lucien Flournoy, the founder of
Flournoy, to the Company's Board of Directors. This acquisition was pursuant to
a definitive asset purchase agreement based on arms length negotiations among
the parties. The assets were acquired for approximately 12.43 million shares of
The Company's common stock, par value $0.10 per share (the "Common Stock"), and
cash on hand of approximately $800,000 which was utilized to repay certain of
Flournoy's debt. The assets acquired include 13 land drilling rigs, 17 rig
hauling trucks, a yard and office facility in Alice, Texas and various other
equipment and drill pipe. The Company hired the majority of Flournoy's operating
personnel. Flournoy utilized and the Company intends to utilize these assets in
contract oil and gas land drilling services.

        The Company agreed to issue additional shares of Common Stock to
Flournoy's shareholders (the "Additional Flournoy Shares") if, and to the extent
that on January 31, 1998, the aggregate market value of one-half of the shares
received by the Flournoy shareholders, plus the gross proceeds from any sales of
Common Stock by the Flournoy shareholders prior to January 31, 1998 is, in
total, less than $12.43 million. If such a shortfall in market value occurs, the
number of Additional Flournoy Shares to be issued will be determined by dividing
the amount of the shortfall by the average closing price of the Common Stock in
each of the ten trading days prior to the first anniversary of the closing.
During such ten trading day period, each of the Flournoy Shareholders will agree
not to sell any shares received by them at closing. The Company will retain the
option of paying any shortfall amount in cash rather than shares of Common
Stock. The Company granted immediate shelf registration rights for the resale of
the Flournoy shares.

      Company are pending.

            (b) VALIDITY OF AGREEMENT; APPROVALS; NO CONFLICT WITH INSTRUMENTS.

      filing or notice under, any provision of any law, rule or regulation,
      court order, judgment or decree applicable to the Company; (ii) will not
      result in the creation of any Encumbrance (other than any Permitted

      violation of, any provision of Applicable Law or regulation which charge
      or violation, if determined adversely to the Company, would materially and
      adversely affect the Business or the results of operations of the Company
      or that might reasonably be expected to materially affect the right of
      Buyer to own the Assets or operate the Business after the Closing Date in
      substantially the manner in which it is currently operated.

      Assets.

            (m) RIGHTS OF THIRD PARTIES. Except as specifically set forth on one
      or more of the Schedules hereto, the Assets are transferable and
      assignable to Buyer as contemplated by this Agreement without the waiver
      of any right of first refusal or the consent of any other party being
      obtained, and there exists no preferential right of purchase in favor of
      any person with respect to any of the Assets or the Business.

            (n) ADDITIONAL INFORMATION. SCHEDULE 3.1(n) hereto contains accurate
      lists and summary descriptions of the following:

                  (i) the names and titles of and salary or current hourly rates
            for all employees of the Company;

                                       11
<PAGE>
                  (ii) all names under which the Company has conducted any
            business or which any of them has otherwise used;

                  (iii) a listing of all performance and similar bonds and
            letters of credit currently posted by, or any certificate of
            financial responsibility or similar evidence of financial
            accountability obtained or procured by, the Company for the purpose
            of operating the Assets or otherwise conducting the Business; and

                  (iv) a schedule showing the Company's tax basis for Federal
            Income Tax purposes in the Assets.

            (o) LABOR MATTERS. The Company has not suffered any strike,
      slowdown, picketing or work stoppage by any union or other group of
      employees. The Company is not a party to any collective bargaining
      agreement; no such agreement determines the terms and conditions of
      employment of any employee of the Company; no collective bargaining agent
      has been certified as a representative of any of the employees of the
      Company; and no representation campaign or election is now in progress
      with respect to any of the employees of the Company. The Company has not
      taken or failed to take any action that is reasonably likely to cause
      Buyer to incur any liability in the event Buyer chooses not to employ any
      of the Company's employees following the Closing. The Company has complied
      in all material respects with all laws relating to the employment of labor
      in the conduct of the Business, including provisions thereof relating to
      wages, hours, equal opportunity and the payment of pension contributions,
      social security and other taxes.

            (p) EMPLOYEE BENEFIT PLANS AND ARRANGEMENTS. SCHEDULE 3.1(p) hereto
      lists all written employee benefit plans and collective bargaining, labor
      and employment agreements and severance agreements or other similar
      arrangements (together with all documents or instruments establishing or
      constituting any related trust, annuity contract or other funding
      instrument), and whether or not legally enforceable, to which the Company
      is (or in the past five years has been) a party or by which the Company is
      (or in the past five (5) years has been) bound, including (1) any
      profit-sharing, deferred compensation, bonus, stock option, stock
      purchase, pension, retainer, consulting, retirement, severance, or
      incentive compensation plan, agreement or arrangement, (2) any welfare
      benefit plan, agreement or arrangement or any plan, agreement or
      arrangement providing for "fringe benefits" or perquisites to employees,
      officers, directors or agents, including benefits relating to automobiles,
      clubs, vacation, child care, parenting or maternity leave, sabbaticals,
      sick leave, medical expenses, dental expenses, disability, accidental
      death or dismemberment, hospitalization, life insurance and other types of
      insurance, (3) any employment agreement, or (4) any other "employee
      benefit plan" (within the meaning of Section 3(3) of ERISA) (each, a
      "Benefit Plan"); provided that terminated agreements with individual
      employees under which the Company has no additional liability are not
      listed. Each Benefit Plan has been maintained and contributed to in
      compliance with the requirements of Applicable Law, except for such
      failures to 

                                       12
<PAGE>
      maintain or contribute that would not, in the aggregate, have a material
      adverse effect on the financial condition of the Company or on the Assets.
      The Company has paid and discharged when due all obligations and
      liabilities arising under such Benefit Plans and Applicable Law of a
      character which, if not paid or discharged, might result in the imposition
      of an Encumbrance (other than a Permitted Encumbrance) or the assertion of
      a liability enforceable against the Assets or the Buyer.

            (q) GUARANTEES. Except as disclosed on SCHEDULE 3.1(q), the Company
      is not a guarantor or otherwise is liable for any liability or obligation
      (including indebtedness) of any other person.

            (r) TRANSACTIONS WITH AFFILIATES. Except as disclosed on SCHEDULE
      3.1(r), no shareholder, director or officer of the Company or any
      associate of any such shareholder, director or officer is currently,
      directly or indirectly, a party to any transaction with the Company
      relating to the Business, including any agreement, arrangement or
      understanding, written or oral, providing for the employment of,
      furnishing of services by, rental of real or personal property from, or
      otherwise requiring payments to any such shareholder, director, officer or
      associate.

            (s) PLAN OF DISTRIBUTION. Except for a distribution of DI Stock to
      the Shareholders upon a liquidation of the Company, the Company has no
      current plan or intention to engage in a sale, exchange, transfer,
      distribution, pledge, or other disposition, or otherwise reduce its risk
      of ownership of, the DI Stock.

      jurisdiction in which its right, title or interest in or to any of the
      assets, or the conduct of the business, requires such authorization,
      qualification or licensing, except where the failure to so qualify or to
      be in good standing in such other jurisdictions would not have a material
      adverse effect on any of its assets, business or the results of operations
      of the Buyer. No actions or proceedings to dissolve the Buyer are pending.

            (b) AUTHORIZATION AND VALIDITY OF AGREEMENT. The execution, delivery
      and performance of this Agreement by the Buyer have been duly authorized

      the Buyer of this Agreement and the consummation by the Buyer of the
      transactions contemplated hereby. This Agreement has been duly executed
      and delivered by the Buyer and constitutes a legal, valid and binding
      obligation of the 

                                       13
<PAGE>
      Buyer, enforceable against it in accordance with its terms, except as the
      same may be limited by bankruptcy, insolvency or other similar laws
      affecting creditors' rights generally and by general equity principles.
      Except as would not constitute a material adverse effect on the
      transactions contemplated herein, the execution, delivery and performance
      of this Agreement by the Buyer and the consummation by it of the
      transactions contemplated hereby (i) will not violate (with or without the
      giving of notice or the lapse of time or both) or require any consent,
      approval, filing or notice under, any provision of any law, rule or
      regulation, court order, judgment or decree applicable to the Buyer; (ii)
      will not conflict with, or result in the breach or termination of any
      provision of, or constitute a default under, or result in the acceleration
      of the performance of the obligations of the Buyer under the charter or
      by-laws of the Buyer, or any indenture, mortgage, deed of trust, lease,
      licensing agreement, contract, instrument or other agreement to which the
      Buyer is a party or by which it or any of its assets is bound or affected;
      and (iii) will not require any consent, approval, waiver, order or
      authorization of, or registration, declaration or filing with, any
      Governmental Entity, except for (x) the filing pursuant to the HSR Act and
      (y) any necessary consents to transfer or assign Permits, to the extent
      the same are transferable or assignable.

            (c) NO APPROVALS OR NOTICES REQUIRED; NO CONFLICT WITH INSTRUMENTS.
      The execution, delivery and performance of this Agreement by Buyer and the
      consummation by it of the transactions contemplated hereby (i) will not
      violate (with or without the giving of notice or the lapse of time or
      both), or require any consent, approval, filing or notice under any
      provision of any law, rule or regulation, court order, judgment or decree
      applicable to Buyer, and (ii) will not conflict with, or result in the
      breach or termination of any provision of, or constitute a default under,
      or result in the acceleration of the performance of the obligations of
      Buyer, under, the charter or bylaws of Buyer or any indenture, mortgage,
      deed of trust, lease, licensing agreement, contract, instrument or other
      agreement to which Buyer is a party or by which Buyer or any of its assets
      or properties is bound.

            (d) CERTAIN FEES. Neither Buyer nor any of its officers, directors
      or employees, on behalf of it, has employed any broker or finder or
      incurred any other liability for any brokerage fees, commissions or
      finders' fees in connection with the transactions contemplated hereby.

            (e) SEC FILINGS. The Buyer has heretofore made available to the
      Company all reports, registration statements and other filings filed by DI
      with the Securities and Exchange Commission since January 1, 1996 (the "DI
      Commission Filings"). As of their respective dates, the DI Commission
      Filings did not contain any untrue statement of a material fact or omit to
      state any material fact required to be stated therein or necessary in
      order to make the statements contained therein, in light of the
      circumstances under which they were made, not misleading. Each of the DI
      Commission Filings was prepared in material compliance with all Applicable
      Laws. The audited consolidated financial statements and unaudited
      consolidated interim financial statements of DI included in the 

                                       14
<PAGE>
      DI Commission Filings present fairly, in conformity with generally
      accepted accounting principles applied on a consistent basis (except as
      may be indicated in the notes thereto), the consolidated financial
      position of DI as of the dates thereof and its consolidated results of
      operations and cash flows for the periods then ended (subject to normal
      year-end audit adjustments in the case of any unaudited interim financial
      statements). Since September 30, 1996, there has not been any material
      adverse change in the business, assets, results of operations or condition
      (financial or otherwise) of DI and its subsidiaries considered as a whole,
      or other material and adverse event or occurrence which, under Applicable
      Law, would necessitate the filing of a report on Form 8- K.

      3.3 SURVIVAL OF REPRESENTATIONS AND WARRANTIES. The respective
representations and warranties of the parties contained herein shall survive the
Closing for a period of eighteen (18) months; provided that there shall be no
expiration of any such representation or warranty as to which a bona fide claim
has been asserted by written notice of such claim delivered to the party or
parties making such representation or warranty during the survival period. This
Section 3.3 shall not at any time relieve any party hereto from the performance
of such party's agreements, covenants and undertakings set forth in this
Agreement. Notwithstanding the above, Section 3.1(k) shall not survive the
Closing.

      3.4 SCOPE OF REPRESENTATIONS OF THE COMPANY. THE COMPANY MAKES NO
REPRESENTATION OR WARRANTY, EITHER EXPRESS OR IMPLIED, AS TO THE MAINTENANCE,
REPAIR, CONDITION, DESIGN OR MARKETABILITY OF THE REAL ESTATE (EXCEPT AS
OTHERWISE PROVIDED HEREIN) OR ANY OF THE VEHICLES, INVENTORY, DRILL STRING, OR
ANY OF THE RIGS OR ANY PORTION THEREOF OR PROPERTY THEREON, INCLUDING, BUT NOT
LIMITED TO, ANY IMPLIED OR EXPRESS WARRANTY OF MERCHANTABILITY OR FITNESS FOR A
PARTICULAR PURPOSE, IT BEING THE EXPRESS AGREEMENT OF BUYER AND THE COMPANY
THAT, EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, BUYER WILL OBTAIN THE
REAL ESTATE AND THE VEHICLES, INVENTORY, DRILL STRING AND RIGS IN THEIR
CONDITION AND STATE OF REPAIR ON THE CLOSING DATE, "AS IS," AND "WHERE IS."

      relationships with persons having business dealings with the Company;

            (b) maintain the Company's books, accounts and records in the usual,

<PAGE>
      the ordinary course of business and consistent with past practice, (iii)

      comply with any applicable Contract under which such drilling rig is
      operating, provided that it is agreed that the Company shall not be
      required to replace inventory or equipment that is lost due to casualty
      and that is not covered by insurance or reimbursed by the operator; and

            (f) not execute drilling contracts on a turnkey basis without the
      prior written consent of Buyer.

Real Estate prepared by a licensed surveyor and (ii) commitments for title
insurance covering the Real Estate issued by the Title Company, setting forth

shown by the surveys or known to the Company or any of its Affiliates, together
with legible copies of all instruments referred to in such commitment as
constituting exceptions to or restrictions upon the fee simple title of the
Company to the Real Estate. If such commitment shall reveal material
Encumbrances affecting Real Estate which are not Permitted Encumbrances, and if
the Company does not take such steps as shall be necessary to cause any material
Encumbrances affecting the Real Estate which are not Permitted Encumbrances to
be removed or cured prior to the Closing, the Buyer may eliminate the affected
Real Estate as an Asset to be purchased by Buyer and reduce the Purchase Price
by the amount allocated thereto on SCHEDULE 2.3. The survey shall (a) reflect
the actual dimensions of, and area within, the Real Estate, the location of all
easements, set-back lines, encroachments or overlaps thereon or thereover, and
the outside boundary lines of all improvements, (b) identify all (except solely
as any such exception relates to encroachments constituting Permitted
Encumbrances), easements, set-back lines and other matters referred to in the

surveyor, (d) reflect that there is access to and from the Land from a publicly
dedicated street or road, (e) be sufficient to cause the Title Company to delete
the printed exception for "discrepancies, conflicts or boundary lines, or

insurance policy to be delivered pursuant to Section 1.3(a) hereof (except
solely as any such exception relates to encroachments constituting Permitted
Encumbrances), (f) reflect any area that has been designated by the Federal
Insurance Administration, the Army Corps of Engineers or any other governmental
agency or body as being subject to special or increased flooding hazards, (g)
show all items of record affecting such property, (h) contain a metes and bounds

<PAGE>
the property description to be included in the special warranty deed and in the
owner's policy of title insurance delivered pursuant to Section 1.3(a) hereof,
the field notes prepared by the surveyor shall control any conflicts or
inconsistencies between such field notes and the legal description in SCHEDULE
1.1(a) hereto.

      4.4 FURTHER ACTIONS. Subject to the terms and conditions hereof, the
Company and Buyer will each use their reasonable best efforts to take, or cause

fully with each other to the extent reasonably required to obtain such consents.
Notwithstanding any other provision hereof, this Agreement shall not constitute
or require an assignment to Buyer of any Contract, Permit, or other right if an
attempted assignment of the same without the consent of any party would
constitute a breach thereof or a violation of Applicable Law unless and until
such consent shall have been obtained.

      4.5 NOTIFICATION. The Company shall promptly notify Buyer in writing and
keep it advised as to (i) any litigation or administrative proceeding filed or
pending against the Company or, to its knowledge, threatened against it, which

Section 4.

States Department of Justice under the HSR Act, will use their reasonable
efforts to obtain an early termination of the applicable waiting period, and

            (a) If any Rig or Vehicle shall become an actual or constructive

      the Closing Date: (i) Buyer shall not be required to purchase such Rig or
      Vehicle, (ii) the Purchase Price shall be reduced by the amount allocated

      such proceeds and claims shall be deemed to be Excluded Assets for all
      purposes hereunder) and (iv) the other provisions of this Agreement shall
      continue to be in effect and the Closing shall take place in the manner
      contemplated herein.

                                       19

      damage or (y) elect to not purchase the Rig or Vehicle and be entitled to

      obligated to purchase the Assets on the Closing Date and the Purchase

with the Real Estate, the Buyer shall have the right to either (i) proceed with

Company or (b) by any party by notice to the other parties in the event that the
Closing Date shall not have occurred on or before January 31, 1997; provided,
however, that if the Closing Date shall not have occurred on or before such date
due to a breach of this Agreement by one of the parties or an Affiliate of 

                                       23
<PAGE>
such party, that party may not terminate this Agreement; and provided further
that if the Closing Date shall not have occurred on or before such date due to a
failure to obtain a termination of the waiting period under the HSR Act, the
Agreement may not be terminated by either party hereto before February 28, 1997.

      7.2 CHANGES FROM DATE OF AGREEMENT TO DATE OF CLOSING The Company shall
have the right and obligation to update any and all schedules, representations,
and warranties to reflect the conduct of the Business and operations of the
Company from the date hereof to the Closing Date (including notification of any
and all litigation that may arise). In the event of a material adverse change in
the Assets or the Business, as its sole remedy Buyer may (a) elect to close and
waive its right to sue for any breach of this Agreement relating to a change
relating to the Assets of the Business disclosed to Buyer on or prior to the
Closing or (b) terminate this Agreement and waive any such right to sue.

      7.3 NO LIABILITIES IN EVENT OF TERMINATION. In the event of any
termination of this Agreement as provided above, this Agreement shall forthwith
become wholly void and of no further force or effect and there shall be no
liability on the part of Buyer, the Company or their respective officers,
directors, or agents, except that the provisions of Section 10.1 and Section
10.11 hereof shall remain in full force and effect, and provided that (except as
provided in Section 7.2 above) nothing contained herein shall release any party
from liability for breach of any provision, covenant or agreement contained
herein.

8.    COVENANTS; ACTION SUBSEQUENT TO CLOSING.

      8.1 POST CLOSING CONSENT. In the event that the Company shall have failed
prior to the Closing Date to obtain consents to the transfer of any Contract,
Permit or other right that cannot be effectively transferred to Buyer without
such consent (a "Consent Required Contract"), the terms of this Section 8.1
shall govern the transfer of the benefits of each such Consent Required
Contract. The Company and Buyer shall use their reasonable best efforts after
the Closing Date to obtain any required consent to the assignment to, and the
assumption by, Buyer of each Consent Required Contract that is not transferred
to the Buyer at the Closing ("Non-assigned Contract"). The Company and Buyer
shall enter into an agreement on the Closing Date with respect to each
Non-assigned Contract providing that until the rights and obligations of the
Company thereunder are transferred to or assumed by Buyer, or, if earlier, until
the termination of such Non-assigned Contract, the Company shall continue to
perform its obligations thereunder and Buyer shall provide such assistance, at
the sole expense of Buyer, as the Company may reasonably request for such
purpose, including the use of personnel and assets (by lease or otherwise) of
Buyer and its Affiliates of the type and quantity that the Company would have
used to perform such Non-assigned Contract had the transactions contemplated by
this Agreement not been consummated. Such agreement shall also provide that in
consideration of the provision of such assistance, the Company shall, promptly
after the payment of any amounts to the Company by the other party to a
Non-assigned Contract, pay such amounts to Buyer after subtracting therefrom the
reasonable direct costs and expenses actually incurred by the Company as a
result of its performance of the Non-assigned Contract. The parties hereto
acknowledge and agree that 

                                       24
<PAGE>
it is the mutual intent of the parties that all benefits and burdens (except
those accrued as of the Closing Date) with respect to the foregoing shall be
borne by Buyer after the Closing Date and, at the Closing, the parties agree to
enter into an agreement to such effect.

      8.2   ACCESS TO BOOKS AND RECORDS.

            (a) Until the third anniversary of the Closing Date, the Company
      shall afford, and will cause its Affiliates to afford, to the Buyer, its
      counsel, accountants and other authorized representatives, during normal
      business hours, reasonable access to the books, records and other data of
      the Company and the Business with respect to periods ending on or prior to
      the Closing Date to the extent that such access may be reasonably required
      by the Buyer to facilitate (i) the investigation, litigation and final
      disposition of any claims which may have been or may be made against the
      Buyer in connection with the Business or (ii) for any other reasonable
      business purpose.

            (b) Until the third anniversary of the Closing Date, Buyer shall
      afford, and will cause its Affiliates to afford, to the Company, its
      counsel, accountants and other authorized representatives, during normal
      business hours, reasonable access to the books, records and other data of
      the Company and the Business and of Buyer relating to the Company and the
      Business with respect to periods ending on or prior to the Closing Date to
      the extent that such access may be reasonably required by the Company to
      facilitate (i) the investigation, litigation and final disposition of any
      claims which may have been or may be made against the Company in
      connection with the Business or (ii) for any other reasonable business
      purpose.

      8.3 MAIL. The Company authorizes and empowers Buyer on and after the
Closing Date to receive and open all mail received by Buyer relating to the
Business or the Assets and to deal with the contents of such communications in
any proper manner. The Company shall promptly deliver to Buyer any mail or other
communication received by it after the Closing Date pertaining to the Business
or the Assets. Buyer shall use its reasonable best efforts to promptly deliver
to the Company any mail or other communication received by it after the Closing
Date pertaining to the assets described in Section 1.2 hereof, and any cash,
checks or other instruments of payment in respect of such assets.

      8.4 SHAREHOLDER AGREEMENTS. At the Closing, Buyer and each of the holders
of outstanding shares of the Company (each, a "Shareholder") shall execute a
Shareholder's Agreement (each, a "Shareholder Agreement") in substantially the
form of EXHIBIT F hereto.

      8.5 COMPANY'S COVENANT NOT TO COMPETE. In order to allow Buyer to realize
the full benefit of its bargain in connection with the purchase of the Assets,
Company will not, at any 

                                       25
<PAGE>
time for a period of three years following the Closing Date, directly or
indirectly, acting alone or as a member of a partnership or as a holder of in
excess of 5% of any security of any class, or as a consultant to or
representative of, any corporation or other business entity,

            (a) engage in any business in competition with the Business as
      conducted by the Company at the date hereof in those geographic areas in
      which such Business is conducted or has been conducted within one year
      prior to the Closing Date; or

            (b) request any present or future customer or supplier of the
      Company or of the Business as conducted by Buyer to curtail or cancel its
      business with Buyer; or

            (c) unless otherwise required by law, disclose to any person, firm
      or corporation any details of organization or business affairs of the
      Company or the Business, any names of past or present customers of the
      Company or any other non-public information concerning the Business, the
      Company or the Assets; or

            (d) induce or attempt to influence any employee of Buyer assigned to
      the conduct of the Business to terminate his or her employment.

The Company acknowledges that in the event the scope of the covenants set forth
in this Section 8.5 is deemed to be too broad in any proceeding, the court may
reduce such scope to that which it deems reasonable under the circumstances. The
parties hereto agree and acknowledge that Buyer would not have any adequate
remedy at law for the breach or threatened breach by the Company or any of their
Affiliates of the covenants and agreements set forth in this Section 8.5 and,
accordingly, the Company further agrees that Buyer may, in addition to the other
remedies which may be available to it hereunder, file suit in equity to enjoin
either the Company or any of its Affiliates from such breach or threatened
breach and consent to the issuance of injunctive relief hereunder. The Company
understands and agrees that the act of Buyer in entering into this Agreement,
and Buyer's covenants and payments hereunder, shall and do constitute sufficient
consideration for the Company to agree not to compete against Buyer as set out
in this Section 8.5.

      8.6 REGISTRATION STATEMENT. The Buyer and DI will prepare and file with
the Securities and Exchange Commission (the "Commission") under the Securities
Act of 1933, as promptly as practicable following the Closing, and will use all
reasonable efforts to have declared effective by the Commission, a registration
statement on Form S-3 (or such other Form as may be required) for the purpose of
registering the DI Stock issued to the Company hereunder, and keep such
registration statement effective for a period ending on the first to occur of
the disposition of all shares of DI Stock subject thereto and two years
following the Closing Date. DI further agrees, as soon as practicable following
the Closing Date, to prepare and file a listing application covering the DI
Stock issued by the Company hereunder with the American Stock Exchange and use
all reasonable efforts to have such DI Stock so listed.

9.    INDEMNIFICATION.

      9.1 INDEMNIFICATION BY THE COMPANY. Subject to the provisions of this
Section 9, the Company shall protect, indemnify and hold harmless Buyer, its
affiliates and each of its and their respective officers, directors and agents

or related costs or expenses, including court costs and attorneys', and
accountants' fees and disbursements, and any federal, state or local income or

Retained Liabilities, and (ii) the breach of any of the representations,
warranties, covenants, or agreements made by the Company in this Agreement,
including the Exhibits and Schedules hereto, or in any certificate or instrument

exceeds $150,000 (it being understood that such Damages shall accumulate until
such time or times as the aggregate of all such Damages exceeds $150,000,
whereupon Buyer shall be entitled to indemnification hereunder for any such
Damages in excess of, but excluding, $150,000); and PROVIDED, FURTHER, that
Buyer shall not be entitled to assert any rights of indemnification with respect
to any breach of the representations and warranties in Section 3.1(k) or any
other representations and warranties with respect to the Company's Real Estate,

Price set forth in Section 4.3.

      9.2 INDEMNIFICATION BY BUYER. Subject to the provisions of this Section 9,
Buyer shall protect, indemnify and hold harmless the Company, its affiliates and
each of its and their respective officers, directors and agents, and each person
who controls the Company, in respect of any Damages to which the Company may
become subject if such Damages arise out of or are based upon the (i) the
Assumed Liabilities, and (ii) the breach of any of the representations,
warranties, covenants or agreements made by Buyer in this Agreement, including
the Exhibits and Schedules hereto, or in any certificate or instrument delivered
by or on behalf of the Buyer pursuant to this Agreement.

      9.3 MONETARY LIMIT ON INDEMNIFICATION LIABILITY. Notwithstanding any other
provisions to the contrary in this Agreement, the liabilities under Section 9.1
of the Company shall be limited to the sum of $10,000,000 cash or, if the
Company so elects shares of DI Stock with a total value of $10,000,000 at the
last reported sale price of the DI Stock on the American Stock Exchange averaged
for the ten trading days prior to the date of payment by the Company.

      9.4 INDEMNIFICATION PROCEDURES. The obligations and liabilities of each
indemnifying party hereunder with respect to claims resulting from the assertion
of liability by the other party or third parties shall be subject to the
following terms and conditions:

                                       27
<PAGE>
            (a) If any person shall notify an indemnified party (the
      "Indemnified Party") with respect to any matter which may give rise to a
      claim for indemnification (a "Claim") against Buyer on the one hand or the
      Company on the other (the "Indemnifying Party") under this Section 9, then
      the Indemnified Party shall promptly notify each Indemnifying Party
      thereof in writing; provided, however, that no delay on the part of the
      Indemnified Party in notifying any Indemnifying Party shall relieve the
      Indemnifying Party from any obligation hereunder unless (and then solely
      to the extent) the Indemnifying Party thereby is prejudiced.

            (b) Any Indemnifying Party will have the right to defend the
      Indemnified Party against the Claim with counsel of its choice reasonably
      satisfactory to the Indemnified Party so long as (i) the Indemnifying
      Party notifies the Indemnified Party in writing within 15 days after the
      Indemnified Party has given notice of the Claim that the Indemnifying
      Party will indemnify the Indemnified Party from and against the entirety
      (subject to any limitations contained in Section 9) of any Damages the
      Indemnified Party may suffer resulting from, arising out of, relating to,
      in the nature of or caused by the Claim, (ii) the Indemnifying Party
      provides the Indemnified Party with evidence reasonably acceptable to the
      Indemnified Party that the Indemnifying Party will have the financial
      resources to defend against the Claim and fulfill its indemnification
      obligations hereunder, (iii) the Claim involves only money damages and
      does not seek an injunction or other equitable relief, (iv) settlement of,
      or an adverse judgment with respect to, the Claim is not, in the good
      faith judgment of the Indemnifying Party, likely to establish a
      precedential custom or practice materially adverse to the continuing
      business interests of the Indemnified Party, and (v) the Indemnifying
      Party conducts the defense of the Claim actively and diligently and in
      good faith.

            (c) So long as the Indemnifying Party is conducting the defense of
      the Claim in accordance with Section 9.4(b) above, (i) the Indemnified
      Party may retain separate cocounsel at its sole cost and expense and
      participate in the defense of the Claim, (ii) the Indemnified Party will
      not consent to the entry of any judgment or enter into any settlement with
      respect to the Claim without the prior written consent of the Indemnifying
      Party (not to be withheld unreasonably), and (iii) the Indemnifying Party
      will not consent to the entry of any judgment or enter into any settlement
      with respect to the Claim without the prior written consent of the
      Indemnified Party (not to be withheld unreasonably).

            (d) In the event any of the conditions in Section 9.4(b) above is or
      becomes unsatisfied, however, (i) the Indemnified Party may defend
      against, and consent to the entry of any judgment or enter into any
      settlement with respect to, the Claim in any manner it reasonably may deem
      appropriate (and the Indemnified Party need not consult with, or obtain
      any consent from, any Indemnifying Party in connection therewith), (ii)
      the Indemnifying Party will remain responsible for any damages the
      Indemnified Party may suffer resulting from, arising out of, relating to,
      in the nature of, or caused by the Claim to the fullest extent provided in
      this Section 9.
